Giles was not happy after manager A.J. Hinch took him out of the game after he allowed three hits to three straight batters to start the inning.

He was so unhappy, he appeared to yell an expletive at Astros manager A.J. Hinch on his way off the mound. It's unclear what exactly was said, but he certainly had some choice words for his manager. Twitter user @ScottEMarvin first pointed the incident out.

Giles came in with a 4-0 lead in the top of the ninth against the A's, but allowed three straight singles to load the bases and was promptly removed for Hector Rondon.

All three runs scored and Oakland tied the game 4-4, which ultimately forced extra innings. Houston ultimately won 6-5 in 11 innings.

Hinch commented on the incident post-game.

"I did hear about it," he said, via the Houston Chronicle. "He was pretty mad in the dugout. I don't know man. That stuff happens in the heat of battle. I'll have to look at it.

"He can let me know if it was directed at me. I didn't hear anything. You can certainly understand I'll address it. It if turns out it was at me, we'll talk about it."

Giles has had a tumultuous season so far with several poignant negative moments. The first incident of note came May 2 when the reliever allowed a three-run, go-ahead homer to Yankees catcher Gary Sanchez and was saddled with a loss. He promptly punched himself in the face on his way off the mound.

Then, May 27, Giles came into the game with an 8-3 lead in the ninth over the Indians and allowed three runs to score before leaving without recording an out. The game was ultimately tied and the Astros lost in extra innings.

Between those two games and the one Tuesday, Giles allowed 10 earned runs while tallying one out. He has allowed 17 runs all season in 34 appearances.

Hinch spoke to the media Wednesday about Giles' demotion, but he did not address the outburst the reliever had when he was taken out of Tuesday's game.

"He's had success in this league, he's had success in this league this year," Hinch told reporters, via MLB.com. "But right now he's got to sort some things out to get back to be the leverage reliever that he can be."

General manager Jeff Luhnow addressed the situation as well, though he also avoided Tuesday's incident.

“As A.J. said, this was a baseball decision," Luhnow said, via MLB.com. "I don’t know what he said. Things that are said between players or between players and staff, that’s a clubhouse issue. That’s dealt with separately. This is a baseball decision."
